This route sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 1,834 PHX to OKC flights, of which SkyWest Airlines flew 833 at 76.3% on time.
Best time to fly PHX to OKC: a 8am–11am departure, ideally on a Wednesday. Flights in that window arrived on time 84.2% of the time and Wednesday flights 79.7%, against 75.5% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Which airline is most reliable on PHX to OKC
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Airthin sample | 1 | 100.0% | — | 0.00% | A+ |
| American Airlinesthin sample | 134 | 85.4% | 66 min | 2.99% | A |

| Southwest Airlines | 866 | 73.1% | 50 min | 0.81% | C+ |
No carrier stands out. SkyWest tops the table at 76.3%, 3 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Best ways to make this trip
The most reliable ways to fly Phoenix to Oklahoma City
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. PHX → OKCPhoenix to Oklahoma City | SkyWest Airlines | 75.8% | 76.3% | 0.60% | 8am–11am, Wed | OO 6320 18:55 |
| 2. PHX → OKCPhoenix to Oklahoma City | Southwest Airlines | 72.5% | 73.1% | 0.81% | 8am–11am, Tue | — |
Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 3 points between the best and worst carrier.

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 59.1% on time, against 84.2% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 619 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 16 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
August is the worst month at 68.2% on time, 16 points below September, the best at 83.7%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. December was the busiest month here, with 169 flights.
Across the week, Wednesday is the strongest day at 79.7% on time and Sunday the weakest at 72.6%, a spread of 7 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 46% of the 28,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 43%Carrier
- 7%National Airspace System
- 4%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 28,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 28,160 reported delay minutes.
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 28,000 delay minutes reported here.
Cancellations are rare at 0.87%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here actually costs
8.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 833 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 80.6% on time across 1,834 flights, 5 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
The sample behind these figures is 1,834 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 83.7% on time and August 68.2%, a swing of 16 points. If the dates move at all, move them out of August before you think about anything else. 1,818 completed flights over 12 months sit behind that.
Common questions
PHX to OKC questions
How often is PHX to OKC delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.5% of the 1,834 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on PHX to OKC?
SkyWest Airlines leads at 76.3% on time across 833 flights. Southwest Airlines is at the other end on 73.1%, a gap of 3 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on PHX to OKC?
The 8am–11am departure window is the strongest at 84.2% on time. The 8pm–5am window is the weakest at 59.1%, 25 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are August delays on PHX to OKC?
August is the weakest month at 68.2% on time, compared with 83.7% in September. Across the year that is 16 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
